Lights dimming/wiring
|
Silver Member Username: RhasslerGilford, NH Post Number: 453 Registered: Dec-04 | Hey, I was reading about the big 3 wiring, and it had me thinking about why my lights are dimming. I have a 200 amp high output alternator, and optima yellow top battery and 1 gauge wiring, and I'm running an orion 1200d (1200 watts rms at 1 ohm) and an alpine amp for my 2 jl 5x7 speakers(about 100/125 watts ish to each speaker(rms). This is all in a '97 ford f-150 ext cab truck. My problem is at night if I turn my system up high like 30/33+ on the volume my lights dim a little bit, its not that bad but its noticible. With the 200 amp alternator I thought I'd be fine. So I'm guessing that the wiring is messed up or something. When i was reading Thanks for the help!! |

If you haven't blown it, you're not pulling over 175 amp of current. putting a 300a fuse isn't going to help. I'm not completely sure of your setup, and I looked at the pics.  but... you need to find where your engine block is grounded.. ugrade that cable with 1/0. find the cable that goes to your fusebox from your alt, upgrade, fusebox to battery, upgrade (that's how mine was in my jeep--alt-fusebox-battery) then upgrade your battery to ground cable)... Your headlights still may dim slightly, especially at idle.. this is OKAY.. the alternator cannot react quickly enough to the amps current demands, thats actually what a capacitor is for!, yes they have a use lol... |

Silver Member Username: RhasslerGilford, NH Post Number: 463 Registered: Dec-04 | lol thanks for the info, I was just gonna go with a battery cap, but then people said that with my alt I shouldnt have any light dimming problems at all and it got me allll confused lol. I might look into those batcap 800's, the people who have them seem to like them. I already have all the wires cept the fusebox-batt wire upgraded to 1 gauge (i'll upgrade that),but will upgrading all the previous 1 gauge wires to 1/0 gauge make a difference? |
